  • Patent number: 11971000
    Abstract: An electric starter system (100) for a motorcycle with a mechanical kick-start device (200) and a transmission main shaft (340) which rotates in a starting and drive rotational direction (x) and the kick-start device (200) has a kick-start pinion configured for axial coupling to a kick-start clutch part (240) which is connected to the transmission main shaft (340) in a torque-transmitting manner. The electric starter system (100) comprises an electric starter motor (110) with a starter shaft pinion (112) that can be driven thereby, which makes it possible to carry out the installation or retrofitting thereof with fewer modifications of the original components, less expenditure of time, and/or easier, and/or faster. This is achieved because a torque of the electric starter motor (110) can be transmitted from the starter shaft pinion (112), preferably at the end face, to the kick-start clutch part (240), in particular via interposed starter gearing (120).
